Dr.Wong is doing a psychophysical experiment to determine the smallest detectable concentration of coffee.He presents some coffee concentrations that are clearly detectable, others that cannot be detected, and some that are just detectable.These presentations are randomized.What method is Dr.Wong using?
A)adjudication
B)constant stimuli
C)inverse thresholds
D)limits

Question

Quizplus · Accepted Answer

Dr. Wong is using the constant stimuli method, where a set of stimuli with varying intensity (in this case, coffee concentrations) are presented in a randomized order to determine the smallest detectable concentration. This method allows for a more accurate determination of the threshold as it minimizes response bias.
